Justin Bieber is offering clarity into his decision to cancel his Purpose tour.

The 23-year-old singer took to Instagram on Wednesday to share a heartfelt message about his past decisions and future hopes, explaining that he needed to take time off in order to be “sustainable.”

“I’m so grateful for this journey with all of you.. I’m grateful for the tours but most of all I am grateful I get to go through this life WITH YOU.!” Bieber began his message. “I have let my insecurities get the best of me at times, I let my broken relationships dictate the way I acted toward people and the way I treated them! I let bitterness, jealousy and fear run my life.!!!”

“I’m VERY aware I’m never gonna be perfect, and I’m gonna keep making mistakes but what I’m not going to do is let my past dictate my future.. What I’m not gonna do is be ashamed of my mistakes,” he continued. “I wanna be a man that learns from them and grows from them.!! I want you all to know this tour has been unbelievable and has taught me so much about myself.. I am reminded of how blessed I am to have a voice in this world. I’ve learned the more you appreciate your calling the more you want to protect your calling.”

J.Biebs went on to state that ending his tour early is allowing him to take the time to work on himself an an artist, man and future husband and father.

“Me taking this time right now is me saying I want to be SUSTAINABLE.. I want my career to be sustainable, but I also want my mind heart and soul to be sustainable. So that I can be the man I want to be, the husband I eventually want to be and the father I want to be,” he wrote. “This message is just an opportunity for you to know my heart, I’m not expecting anyone to understand, but I do want people to have an opportunity to know where I am coming from!“
